Rafael gave an awesome talk about using Composer the right way!
Rafael did a great job with this talk. A lot of people new to the subject are having a hard time how to use composer correctly. He addresses all those issues in this talk in a very clear way. The cookbook he's writing is a good initiative from which a lot of developers could benefit.
Also no negative feedback for the speaker skills. Well presented, speaks loud and clearly. And he's a nice person too.
So that makes another 5 start rating I guess? :)
Great talk about composer. I liked the part about semantic versioning the most, because there are a lot of developers that still don't get it right.
